We just came back from the Tetons - but will remember this for the next trip! (Last summer we did about 200 miles on dirt roads on our way to Las Vegas!)
I did a job out of Salmon, Idaho and we blew two tires on the company vehicle in one day. We drove a lot slower after that, but ended up buying a whole set of tires (used) so we would be able to drop the flats at the shop and go on up to work. Lots of sharp shale rock in the area which ends up in/on the roads. Beautiful country - thanks for the photos.
Well, I was just running the standard 4-ply tires that came with the vehcile (my mistake there). Have since bought four much more aggressive tread, much stronger ply tires. The really rough ride up to Burnt Knob weakened the stock tires and then the road going up Salmon Mountain had a sharp rock poke on through.
